In reply to Emilio Bachini:
I've not got much to offer, but I did Atomic Bong in June 79, the same day we did a new route on the banned section in error (Thunderchild at HVS). I remember Atomic Bong being decent. Also did Cygnus X1, the girdle of the main buttress, which was really entertaining, later that month. That did an easy approach pitch on the right of the buttress before traversing in three pitches. One involved a quite spectacular descent and the last was quite delicate (probably joining Atomic Bong if memory is anything to go by.... If you can get hold of Dave Knighton or Dave Cronshaw, they would probably know all the details.
